SMRE Engineering of Italy, figured this was an inefficient way to do things, but also, the lack of transmission and shifting took some of the enjoyment out of the ride, so they built the IET System, an electric motor with a six speed mechanical transmission and clutch, a mechatronic motorcycle. Software can map the motor's performance characteristics for whatever you might need or want while allowing a smaller motor and battery pack than necessary without the transmission since multiple gears keeps the motor in the most efficient range. The smaller battery pack makes up for the additional weight of the transmission.
